Summary
Subject deals with characteristics components that are used at power semiconductor converters, not only at dissimilarity from typical low power components but so application of modern power switch off components that are bipolar and unipolar transistor, IGBT and thyristor GTO, MCT and IGCT.
Learning Outcomes of the Course Unit
The main goal of the subject is to obtain theoretical knowledge from power semiconductor devices areas and practical experiences with dimensioning and applications. Obtained knowledge employ to practical use for the design of various electronics equipments, as switching sources, various type regulators and power semiconductor converters. Learned information creates the knowledge base of bachelor, especially if his topic is aimed in area of power electronics systems application .
